ITD Projects Southwest Idaho Idaho 55 Lardo Bridge

BRIDGE CLOSED: Oct. 15 - Nov. 26


Idaho 55 Lardo Bridge
Lardo Bridge
Project Description:

Project Number: A013(392)

Project Key Number: 13392)

The 83-year-old Lardo Bridge on Idaho 55 at milepost 145 near the McCall City Park on the southwest shore of Payette Lake is being replaced.

The department has developed a conceptual design that maintains McCall's character, protects natural resources and preserves scenic amenities.

When completed, the project will:

  • Replace the existing Lardo Bridge, built in 1931
  • Replace roadway approaches to the bridge
  • Provide bicycle and pedestrian facilities on both sides of the bridge
  • Serve as a gateway to the city of McCall

The new bridge will accommodate one lane of traffic in each direction. The existing bridge is 200 feet long and 38 feet from one outside edge to the other. The new bridge will be approximately the same length, but may be up to 50 feet wide.

ITD will use a design-build method for this project. Design-build is a streamlined process in which the design team and construction team work together simultaneously. This method allows for innovative methods of construction and results in quicker project completion. Lardo Bridge is only the second design-build project in Idaho.

The team of Ralph L. Wadsworth Construction and Lochner was selected March 27, 2014 as the design-build firm for the Lardo Bridge replacement project. Ralph L. Wadsworth will mobilize and begin construction on the Idaho 55 North Fork Payette Bridge the week of July 14.

The team of Ralph L. Wadsworth and Lochner will use an accelerated bridge construction method called lateral slide, where the new bridge will be constructed north of the existing structure and then slid into place after the old bridge is demolished. This construction method reduces a full closure of the bridge by months.

Accelerated bridge construction uses innovative planning, design, materials, and construction methods in a safe and cost-effective manner to reduce the onsite construction time, and impacts to the community, businesses and the traveling public.

The Idaho Transportation Department is fully funding this project through the State Highway System Restoration Program, which is reimbursed with a share of Idaho''s federal-aid highway funds. The total cost for the project is approximately $5 million. The construction/design contract is for $3.64 million and the remaining amount includes project development and administration.

Construction Schedule:

Although construction has not yet begun in earnest, some preliminary construction activities began in May 2014.

Although construction is not expected in earnest until this fall, some preliminary construction activities are expected to begin in May and continue through the summer. These preparatory activities will take place all summer, but impacts to the traveling public will be minimized as much as possible - See more at: This Link
